The date of discovery initially posted on TOCP for this supernova candidate is wrong. We discovered this object on November 14.67 2014 UT in the Tsinghua University-NAOC Transient Survey (TNTS), and the magnitude of the object on unfiltered CCD was about 18.3 mag.

2014 11 23.7385

This transient was observed on 2014 11 23.7385 by G. Masi and P. Catalano, remotely using the 17"-f/6.8 robotic unit part of the Virtual Telescope Project facility, at Bellatrix Astronomical Observatory in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 17.8 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 08.73; 21.0 (J2000.0, mean residuals of 0.2" on both axes).
